There are lots of updates in Melodyne 4. We worked with Celemony throughout the V4 release cycle to ensure tight integration in SONAR. Although M4 with work in X3, some of the newer features and UI in Melodyne will require the latest version of SONAR to work fully. Also there are numerous bug fixes and improvements to ARA in the latest SONAR.
I haven't verified this, but it seems like one of the key new M4 features is not fully compatible with Sonar yet: the tempo-extraction and -manipulation seems very cool but would obviously be far more useful if the tempo information could be shared between the programs in some way... apparently this is possible in Studio One, according to
this thread, but I don't have any way to check that.
It would be great to know if this will make it to Sonar in the foreseeable future...
